The same route forty times, which is when it starts being interesting
The route
Four miles, a loop, done roughly weekly for ten months. Nothing remarkable about it and that is largely the point.
What changed
Eleven things worth noting, of which nine are seasonal and two are not. The two are a fallen ash and a new fence line.
What did not
Everything else, which is the harder observation and the one that only becomes visible against a long record.
